White-collared Pigeon

Rarely found north of cold subantarctic waters; ranges south to pack-ice in summer. Adult has a gray head, thick black underwing margins like much commoner Black-browed Albatross. Immatures look similar to Black-browed overall, but told by black bill that soon develops yellow along top, and often with variable gray hood. Yellow bill edges narrower than the more lightly built Buller’s Albatross, which occurs to the north but is often mistaken for Gray-headed.

Medium-sized white egret. Breeding adult has bright blue loral skin, a pinkish-orange bill, and long frilly plumes on the head, neck, and back. Nonbreeding adult lack plumes and has dull greenish legs and bill. Nonbreeding birds can be confused with Little Egret, but note Chinese Egret's thicker bill, proportionally stouter legs, orangish base to the bill, and dark lores with a shallow crook between eyes and bill. Light morph of Pacific Reef-Heron may also be similar, but average much thicker-billed and thicker-legged than Chinese. Moves between craggy islands and coastlines when breeding; winters in mangroves, estuaries, and mudflats.

A small, mostly grass-green bee-eater with a canary-yellow throat separated from buff underparts by a black line across the throat. Singles and pairs occupy grassy savanna and wetland edges. They often perch lower than 1.5 m above the ground, and dart around hunting flying insects, then returning to the same small twig. Calls include a sibilant “s-lip” and other high-pitched notes. The Blue-breasted Bee-eater is slightly larger and has a white patch on the cheek. The much larger Cinnamon-chested Bee-eater has burnt orange underparts, and it prefers highland forest above 1800 m.
